Cakes that can be cooked whilst camping?+1 on the Dutch Oven. There are models specifically designed for use in a campfire. They have feet on the bottom and a recessed top. That way hot coals can be placed above and below. They're heavy since they're made of cast iron or cast aluminum, so not for backpacking ;~)

Which vegetables to use for stock?From Michael Ruhlman's, "The Elements of Cooking". "Broths (bouillons) are distinguished from stocks in that a broth is intended to be served as is whereas a stock is the foundation for other preparations." p.74 So, you can have either vegetable stock or vegetable broth. Neither one will have bones. There is actually another post on the site discussing the differences between stock and broth.
